Abstract (en)
Provided is a method of forming a device having optical functionality. The method includes forming an optical waveguide over a substrate by providing a clad layer and a core over the substrate. The clad layer includes a polymer having units of the formula (RSiO 1.5 ), wherein R is a substituted or unsubstituted organic group, and a photoactive component. A portion of the clad layer is photolithographically patterned. Also provided is a method of forming a printed wiring board having optical functionality. The invention has particular applicability in the electronics industry for forming optoelectronic devices.
